Ten Go Fish
1st gr.
This is a good game for students to become familiar with combinations of ten. It is played like Go Fish. Players are dealt 5 cards and try to
make a combination of ten by asking their partner for a card that when added to
one of their cards makes ten. For example, if one of my cards is an 8 then I am going to ask for 2. Pairs of cards making ten are placed on the table
and the player must draw another card from the deck. If that card makes ten with
a card the player already has, he/she puts the pairs down again and draws another card.

If a player uses up all of their cards, but there are still cards in the deck, the
player must draw two cards from the deck. The object of the game is to use up all
the cards in the deck and have no cards in hand. To reinforce the combinations of ten,
I also had players write down their combinations of ten at the end of the game.
Students may have trouble holding
all their cards so their opponents do
not see them. I use a card holder
which I also use for Making Words
activities. It is a file folder cut to be
about 6 inches tall and then folded
up and stapled to make an inch deep
pocket across the bottom of the folder.

To make the game more challenging,
have three to four students play together.
It makes it harder to remember what cards others have asked for.
